USN-2732-1: Linux kernel (OMAP4) vulnerability
03 September 2015
- linux-ti-omap4 - Linux kernel for OMAP4
Benjamin Randazzo discovered an information leak in the md (multiple
device) driver when the bitmap_info.file is disabled. A local privileged
attacker could use this to obtain sensitive information from the kernel.
The problem can be corrected by updating your system to the following package versions:
After a standard system update you need to reboot your computer to make
all the necessary changes.
ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed. If
you use linux-restricted-modules, you have to update that package as
well to get modules which work with the new kernel version. Unless you
manually uninstalled the standard kernel metapackages (e.g. linux-generic,
linux-server, linux-powerpc), a standard system upgrade will automatically
perform this as well.
